About the role

Senior Engineer to build the foundational architecture behind AI research agents, including SDKs, APIs, execution frameworks, sandboxed execution, benchmarking, and evaluation tooling for researchers to build and scale intelligent systems.

Responsibilities

  • Design and build the frameworks, SDKs, and execution surfaces that define how agents, tools, and services interact across our research platform
  • Build infrastructure for sandboxed agent execution, enabling researchers to safely run, inspect, and iterate on agent workflows at scale
  • Design and maintain evaluation and benchmarking frameworks that measure the performance of individual agent components and end-to-end systems
  • Develop abstractions and developer-facing tooling that let research scientists build, compose, and deploy agents without owning the underlying infrastructure
  • Drive continuous improvements in reliability, observability, and cost-efficiency across the systems agents run in and depend on
  • Engage in the entire software development lifecycle, from ideation and design to implementation and testing to deployment and operational support, with ownership
  • Collaborate across engineering and research teams to ensure maintainability, test coverage, and robust deployment
  • Communicate effectively across engineering, product, and research teams to align priorities and drive projects to completion

Qualifications

  • Bachelor's degree and 8+ years of technical experience; relevant experience may substitute for education
  • Strong Python engineering skills, with experience building production services and developer-facing tools
  • Experience designing SDKs, APIs, or frameworks that other engineers built on top of and adopted
  • Hands-on experience building or operating agentic systems – agent orchestration, tool integration, sandboxed execution, memory management, or the surfaces agents run in and consume
  • Experience designing evaluation or benchmarking infrastructure that measures system or component performance
  • Experience with cloud infrastructure (AWS, GCP, or similar), containerization, and deployment automation
  • Strong communication skills and a sense of ownership for results
